I just went ahead and replaced my TRX's with a set of tires and wheels for $928 (15") mounted, balanced, and delvered. They look better, are cheaper after the second set or tires, last longer, and ride and drive real nice. (Anybody want a set of Metric rims?) Anybody with the Chilton manual: Go out and get the Bentley manual immediately. I picked up the 5 series Bentley and it is MUCH better than the Chilton, even if it costs over $40. Chris Guy 86 535i
